Add NLS catalogs support to strerror(), strerror_r() and strsignal().

Back out the `hiding' of strlcpy and strlcat. Several people

vocally objected to this safety belt.

`Hide' strlcpy and strlcat (using the namespace.h / __weak_reference

technique) so that we don't wind up calling into an application's
version if the application defines them.

Inspired by:	qpopper's interfering and buggy version of strlcpy

Optimize errstr() by reducing the number of times it walks a string.

As a side effect, it makes the code easier to read and requires less
pointer arithmetic.

Stylistic changes:

2002-12-20T05:26:10+00:00

o Fix an English error (comma splice) and poorly worded sentence.
o Fix KNF ordering of variables (pointers come before arithmetic types).
o Restore hand-optimization of sizeof()-1, instead of strlen().
o Remove unneeded local variables in strerror_r().

Rearrange strerror() so that its itoa procedure can be used with

2002-12-18T16:53:31+00:00

strerror_r().  Doing this allows us to ensure that strerror_r() always
fills the supplied buffer regardless of EINVAL or ERANGE errors.

strerror()'s semantics have changed slightly such that an argument of
0 is now considered invalid and errno is set to EINVAL.

Remove internal regression test for strerror() and strerror_r().  This
will be reincarnated in src/tools/regression/lib/libc/string.

In strerror(3), add a comment about strerror()'s bogus return type.
